ABSTRACT

A security barrier comprising a front panel and a bottom panel, the security barrier comprises a reinforcement panel, which in installed state of the security barrier, covers at least part of the front panel, in order to double the said at least part of the front panel and method of installing such a security barrier.

FIELD OF THE DISCLOSURE

The present disclosure relates to a security barrier comprising a frontpanel and a bottom panel, wherein in installed state of the securitybarrier the bottom panel is connected at an angle to the front panel.

The present disclosure also relates to a method of installing a securitybarrier on the ground, wherein a front panel and a bottom panel areprovided, wherein the front panel is erected and the bottom panel isplaced on the ground.

BACKGROUND

Security barriers are used to prevent people, animals etc. fromintruding in a certain area. Many countries have one or several securitybarriers for protecting their national borders as such in order toprevent people from other countries from immigrating. Also industrialsites, nature reserves, military sites or other areas/grounds aresurrounded with security barriers to prevent intrusion of people andanimals. These security barriers need to be solid and strong in order toeffectively stop potential intruders. They also need to be able toabsorb impacts form vehicles such as cars, trucks etc. because peoplecan attempt to destruct a part of the security barrier by crashing intothe security barrier with a moving vehicle. Security barriers can beused for temporary, semi-permanent or permanent access protection ofareas.

A common type of such a security barrier is a gabion-type securitybarrier comprising several front panels, side panels, bottom panels andrear panels. These security barriers have several compartments eachconfined by a said front panel, two consecutive side panels, a saidbottom panel and a said rear panel. By placing a weight in thesecompartments, a said security barrier is kept in place. These securitybarriers have a certain strength and rigidity. These security barriersare not really apt to absorb impacts from moving vehicles. They are alsoprone to rupturing at the level of the connection of the differentpanels, when impact forces are exerted on them by moving vehicles. Anexample of such a security barrier is described in WO 2008/020247.

SUMMARY

It is therefore an object of the invention to provide a security barrierwhich is strong and solid and which is also apt to absorb impact forcesexerted on them, such as impact forces caused by moving vehicles. Anobject of the invention is also to provide a method of installing such asecurity barrier.

The object of the invention may be achieved by providing a securitybarrier comprising

-   -   a front panel and;    -   a bottom panel;        wherein, in installed state of the security barrier, the bottom        panel is connected at an angle to the front panel, and wherein        the security barrier comprises a reinforcement panel, which in        installed state of the security barrier, covers at least part of        the front panel, in order to double the said at least part of        the front panel.

With ‘connected at an angle’ it is indicated that the panels do notextend in the same plane. The reinforcement panel covers and doubles atleast part of the front panel. For this, the reinforcement panelpreferably extends substantially parallel to the front panel. The anglebetween the reinforcement panel and the bottom panel is thensubstantially the same as the angle between the front panel and thebottom panel. By doubling at least part of the front panel, said atleast part is strengthened and reinforced. An impact force exerted onthe security barrier, for example on the front panel, will therefore bebetter absorbed and guided throughout the security barrier. Also thereis less risk that the security barrier will rupture when an impact forceis exerted on it.

In a preferred embodiment the reinforcement panel is connected to thefront panel. Because of this connection, an impact force exerted on thesecurity barrier, will be better absorbed.

Preferably, in installed state of the security barrier, thereinforcement panel covers at least the front panel adjacent to theconnection of the front panel to the bottom panel. Vehicles normallydrive on the ground on which the security barrier is placed. Alsonormally the bottom panel is placed on the ground. When the front panelis several meters high, this means that a vehicle, which crashes intothe security barrier, will only contact a lower portion of the securitybarrier. It is therefore only necessary to double a lower portion of thefront panel. By covering only a part of the front panel, material can besaved and installation of the security barrier can be simplified.Further preferably the reinforcement panel is connected to the bottompanel. Forces acting upon the security barrier are then also well guidedfrom the reinforcement panel to the bottom panel, such that impactforces can be well absorbed.

In a preferred embodiment the security barrier is composed of at leasttwo construction units, wherein a first construction unit of the atleast two construction units comprises the front panel and wherein asecond construction unit of the at least two construction unitscomprises the bottom panel and the reinforcement panel, wherein thesecurity barrier can adopt at least two configurations, a firstconfiguration being a compact configuration wherein the first and thesecond construction unit are separated from each other and a secondconfiguration in installed state of the security barrier wherein thefirst and the second construction unit are connected. The firstconfiguration is more compact and thus suitable for transport andstorage. The security barrier can thus be delivered on site in its firstconfiguration and then be transformed to its second configuration. Thesecurity barrier can comprise in its first configuration severalseparate first construction units and several second construction unitswhich are connected to each other when installing the security barrier.By making use of several separate first and second construction units,the security barrier can be made very compact. With several standardizedfirst and second construction units, it is also simple to create asecurity barrier of the desired length.

In a very preferred embodiment the reinforcement panel is pivotallyconnected to the bottom panel and the second construction unit is foldedin the first configuration. The pivotal connection ensures that thesecond construction unit can be folded and thus can be made morecompact. Preferably the panels are pivotally connected to each other atthe level of their edges. The dimensions of the reinforcement panel thenpreferably do not exceed the corresponding dimensions of the bottompanel. Further preferably the first construction unit comprises multiplesaid front panels and the second construction unit comprises multiplesaid reinforcement panels and at least one said bottom panel. The frontpanels can also be consecutively pivotally connected to each other, suchthat they can be folded.

Preferably the security barrier comprises side panels which, ininstalled state of the security barrier, are connected at an angle tothe front panel and are connected at an angle to the bottom panel. Theside panels provide additional strength and solidity. They also work aswind bracing. Forces acting upon the security barrier, for example uponthe front panel(s), are here also guided through the side panels suchthat impact forces can be better absorbed.

In installed state of the security barrier, the side panels preferablycomprise unconnected edges, wherein at least one said edge is at leastpartially reinforced with a profile. A said profile causes the sidepanel to be less prone to inclination when forces are acting upon thesecurity barrier. The profile thus reinforces the side panels, so thatimpact forces acting upon the security barrier can be better withstoodand absorbed. Preferably every unconnected edge has such a profile andpreferably each profile extends over substantially the entire length ofa said unconnected edge.

Further preferably a said profile is a U-shaped profile. This is asimple form which can be easily manufactured and be put upon a saidunconnected edge. Also with U-shaped profiles the best results areobtained. With H-shaped profiles and L-shaped profiles good results canbe obtained. However H-shaped profiles comprise more material thanU-shaped profiles to provide the same additional strength to thesecurity barrier.

In a preferred embodiment with side panels, the first construction unitcomprises at least two said side panels, which are pivotally connectedto the front panel of the first construction unit. The pivotalconnections ensure that the first construction unit can be folded andthus can be made more compact. Preferably edges of the side panels arepivotally connected to an edge of the front panel. The dimensions ofeach side panel also preferably extends within the correspondingdimensions of the front panel.

In a very preferred embodiment the security barrier comprises astrengthening panel, which in installed state of the security barrier isconnected to the front panel and two consecutive said side panels, at acertain distance from the bottom panel. This strengthening panel ensuresthat impact forces exerted on the security barrier, for example on thefront panel(s), are well absorbed by the side panels. The strengtheningpanel itself also absorbs said impact forces. Also the risk of rupture,when impact forces are exerted on it, is low.

More preferably the second construction unit comprises the strengtheningpanel. This strengthening panel is than preferably pivotally connectedto the reinforcement panel of the second construction unit. When thebottom panel is then also pivotally connected to the reinforcementpanel, the second construction unit can be compactly folded. Also such asecond construction unit can be easily connected to the firstconstruction unit by unfolding the second construction unit, placing thereinforcement panel against the front panel and for example connectingthe reinforcement panel to the front panel.

Further preferably the strengthening panel extends, in installed stateof the security barrier, substantially parallel to the bottom panel.Impact forces are well absorbed when the strengthening panel extendsparallel to the bottom panel.

In a specific embodiment the front panel, the bottom panel, thestrengthening panel and the reinforcement panel have rectangular shapesand the side panels have a pentagonal shape, wherein one part of eachside panel has a right-angled triangular shape and is located above thestrengthening panel in installed state of the security barrier and inwhich the other part of each side panel has a rectangular shape and islocated below the strengthening panel in installed state of the securitybarrier. The angles between the front panel and the bottom panel, thefront panel and the side panels, the strengthening panel and the frontpanel and between the strengthening panel and the side panels, arepreferably 90°. A security barrier according to this specific embodimentis strong and solid and is well apt to absorb impact forces exerted onit by for example moving vehicles.

The said one part with a right-angled triangular shape is just ascapable of withstanding forces as if it were rectangularly shaped, withthe same dimensions as the dimensions of the straight sides of the rightangled triangle. In addition it contains less material. A right-angledtriangular shape is also easy to produce. The said other part has arectangular shape in such a way that in combination with thereinforcement panel, and the bottom panel, a container can be formed. Inan alternative embodiment the side panels have a stair shape.

Preferably the bottom panel is connected to at least three said sidepanels. In such an embodiment more than two side panels rest on thebottom panel. This ensures that the bottom of the security barrier isfirm and solid such that the security barrier is well apt to absorbimpact forces.

In a preferred embodiment, in the installed state of the securitybarrier, the security barrier comprises at least one container, confinedon the bottom by the bottom panel, on its sides by two said side panelsand on the front by the reinforcement panel, wherein the back of thecontainer is open such that the container is accessible from the back.To provide extra strength and stability to the security barrier, extraweight can be placed on the bottom panel. With an open back this can bedone easily by approaching the security barrier from the back andplacing extra weight on the bottom panel. There is then no back panelthat complicates the placing of extra weight on the bottom panel.

The bottom panel and the reinforcement panel are preferably covered witha UV-resistant material, such as geotextile, plastic, coir mat, . . . .If side panels are present, the side panels are also preferablypartially covered with said UV-resistant material. In this manner it ispossible to place something upon the bottom panel which is notUV-resistant, because the UV-resistant material will protect it. If aweight is placed on the bottom panel and/or if a container (whenpresent) is filled, this UV-resistant material shields said weight orsaid container. Someone standing in front of the security barrier andlooking at the front panel, will not see the weight and/or the inside ofthe container.

Very preferably the said panels are mesh panels. The mesh panels can forexample comprise a first set of wires extending substantially parallelto one another and a second set of wires extending substantiallyparallel to one another, wherein the wires from the first set and thesecond set intersect, and where these intersect are mutually attached.With the term ‘wires’ elongate elements or rod-shaped elements areindicated. These wires are, for example, formed by pulling force or byextrusion and they can be made out of metal, plastic, etc. The wires canfor example be welded together where they intersect in order to attachthe wires. Welding indicates every operation or treatment, whether ornot with the addition of welding materials or gluing materials orproducts and whether or not accompanied by a (local) heating of theparts to be connected, which creates a durable connection withoutexternal coupling means and with a substantially mechanical connectingfunction. The mesh panels can also be produced by making holes in solidpanels and by stretching these panels as such to create a wire-shapedpattern.

Mesh panels can easily be manufactured in the desired strength andfirmness. Also mesh panels comprise openings between their wires.Material can thus be saved. When monitoring a border or a protected areait is desired that one can see what is happening on the other side ofthe security barrier. With a security barrier comprising mesh panels,one can easily look through the security barrier to see what ishappening. When it is not desired that people can look through thesecurity barrier, the mesh panels can easily be blinded.

Further preferably, the wires of the first set are arranged, in asystematic way, alternately on both sides of the second set of wires. Bysystematically providing wires from the first set alternately on oneside and on the other side of the wires from the second set, a strongersecurity barrier is obtained.

The object of the invention may also be achieved by providing a methodof installing a security barrier on the ground, wherein a front paneland a bottom panel are provided, wherein the front panel is erected andthe bottom panel is placed on the ground and wherein a reinforcementpanel is provided and at least part of the front panel is covered anddoubled by the reinforcement panel. By placing the bottom panel on theground, it is indicated that the bottom panel is placed upon a groundsurface. This surface may be located at ground level. However, it isalso possible that a ditch or the like is dug out, before installing thesecurity barrier. In this latter situation the security barrier isinstalled in this ditch and the bottom panel will at least be partiallylocated below ground level. With the method according to the invention astrong security barrier is obtained. As already indicated in thedescription of the security barrier according the invention, a saidreinforcement panel, that covers and doubles at least part of the frontpanel, strengthens the front panel and ensures that the security barrieris well apt to absorb impact forces exerted on it. Thus by simplyproviding in a reinforcement panel that doubles at least part of thefront panel, a security barrier with the desired properties is obtained.With such a method also existing security barriers can be turned into asecurity barrier according to the invention.

In a preferred embodiment a first construction unit comprising the frontpanel is provided and a second construction unit comprising the bottompanel and the reinforcement panel is provided, wherein the first and thesecond construction units are connected to each other by connecting thebottom panel to the front panel and connecting the reinforcement panelsubstantially parallel to the front panel. With such a method thesecurity barrier can be easily erected starting from a compact form,which can easily be transported and stocked.

Further preferably the second construction unit is provided in a firstposition where the bottom panel and the reinforcement panel arepivotally connected to each other and folded and the second constructionunit is unfolded before connecting it to the first construction unit. Insuch a method, the bottom panel and the reinforcement panel are soprovided that they are pivotally connected to each other, allowing themto be delivered in a compact and folded manner. Preferably they arepivotally connected to each other at the level of their edges and alsopreferably the dimensions of the reinforcement panel do not exceed thecorresponding dimensions of the bottom panel.

In a preferred embodiment the first construction unit is provided withat least two side panels, wherein during the connection of the first andthe second construction unit, the side panels are connected to thebottom panel and the reinforcement panel. By providing side panels, asecurity barrier with additional strength and solidity can be erected.These side panels also work as wind bracing. Such a security barrier isalso better apt to absorb impact forces exerted on it.

Further preferably, the first construction unit is provided in a firstposition where the side panels are pivotally connected to the frontpanel and folded and the first construction unit is unfolded beforeconnecting it to the second construction unit. Preferably the sidepanels are pivotally connected to the front panel at the level of theiredges and also preferably the dimensions of the side panels do notexceed the corresponding dimensions of the front panel.

Also further, in a very preferred embodiment, the second constructionunit is provided with a strengthening panel which is pivotally connectedto the reinforcement panel, and during the connection of the first andthe second construction unit the strengthening panel is connected to theside panels and the front panel. By providing such a strengtheningpanel, the installed security barrier will have more strength andsolidity. The security barrier is also better apt to absorb impactforces exerted on it. The strengthening panel is pivotally connected tothe reinforcement panel such that the second construction unit can bedelivered compactly.

In a preferred embodiment, during the connection of the first and thesecond construction unit, a container confined by the bottom panel, thereinforcement panel and the side panels is formed, and the container isfilled. The container is fit to be filled, for example by a weight. Byfilling the container, weight is placed on the bottom panel, such thatthe security barrier becomes more solid and is strengthened. Thesecurity barrier is then apt to absorb a greater impact force exerted onit. For example the weight can be a concrete block, a filled (big) bag,such as a bag filled with sand. If a filed bag is used as weight, thefilled bag is preferably closed when using the security barrier, suchthat when an impact force is exerted on the security barrier, the bagremains filled and the bag retains its weight as such limiting theamount of movement of the security barrier, when experiencing impactforces. The bag can also be placed empty in the containers and thenlater filled e.g. with material surrounding the security barrier such assand, rocks, etc.

The said bag is preferably made of a water-permeable material such asfor example geotextile, coconut coir, perforated plastic, perforatedmetal, woven plastics or woven fibers. The bag should let water through,but should not let through the material with which it is filled. This isespecially important if the bag is filled with sand. Because of thewater permeability, the occurrence of water logging is avoided.

Further preferably, the container is filled before the strengtheningpanel is connected to the side panels. When the strengthening panel isnot connected to the side panels, the container is easily accessible.

Preferably the bottom panel and the reinforcement panel are pivotallyconnected to each other by means of a spiral that connects an edge ofthe bottom panel with an edge of the reinforcement panel and a bottomedge of the front panel is provided with a spiral, wherein the saidspirals are brought together until they engage in one another andwherein a rod is fitted in the said spirals for interconnecting thespirals in order to connect the bottom panel and the reinforcement panelto the front panel. By placing a rod into two interconnected spirals, asolid and strong connection between the panels is obtained, such thatthe security barrier can absorb greater impact forces and the securitybarrier is less likely to rupture when absorbing an impact force. Alsowith such a method it is easy to install the security barrier quickly.Further preferably, many of the interconnected panels are connected toeach other with the aid of spirals. For example if the security barrieris composed of a said first construction unit and a said secondconstruction unit, the connected panels of each construction unit arepreferably interconnected to each other with the aid of spirals and thetwo constructions units are connected to each other by engaging spiralsof the first construction unit with spirals of the second constructionunit and putting rods through them.

In a very preferred embodiment the security barrier is a securitybarrier according to the invention as mentioned above.

The security barrier (1) of FIGS. 1 and 2 comprise one bottom panel (3),three front panels (2), three side panels (5), three reinforcementpanels (4) and three strengthening panels (6). All these panels (2, 3,4, 5, 6) are mesh panels. Those panels (2, 3, 4, 5, 6) are representedas a white surface. The meshes would make the figures unclear. Also notall panels (2, 3, 4, 5, 6) are indicated with their number for clarityreasons.

As can be seen in FIGS. 1 and 2, each front panel (2) is connected at anangle of 90° to the bottom panel (3), one or two said side panels (5)and a said strengthening panel (6). Further the bottom panel (3) isconnected at an angle of 90° to the three side panels (5) and the threereinforcement panels (4). Each strengthening panel (6) is furtherconnected at an angle of 90° to one or two side panels (5) an to a saidreinforcement panel (4).

Each reinforcement panel (4) is connected parallel to a said front panel(2) such that it covers a bottom part of the respective front panel (2),that is adjacent to the connection between the bottom part (2) and therespective front panel (2), in order to double the bottom part of thesaid front panel (2). The unconnected edges of the side panels (5) areeach reinforced with a U-shaped profile (8). The strengthening panel (6)extends substantially parallel to the bottom panel (3).

The front panels (2), the bottom panel (3), the strengthening panels (6)and the reinforcement panels (4) have rectangular shapes and the sidepanels (5) have a pentagonal shape, wherein the upper part of each sidepanel (5) has a right-angled triangular shape and is located above thestrengthening panels (6) and in which the lower part of each side panel(5) has a rectangular shape and is located below the strengtheningpanels (6).

The security barrier (1) comprises two containers which are confined onthe bottom by the bottom panel (3), on its sides by the lower parts oftwo said side panels (5), on the top by a said strengthening panel (6)and on the front by a said reinforcement panel (4), wherein the back ofthe container is open such that the container is accessible from theback. Further the security barrier (1) can have a fourth side panel (notshown), connected to the front panel (2) and to the strengthening panel(6) and the reinforcement panel (4) which are only connected to one sidepanel (5) in FIGS. 1 and 2, such that the security barrier (1) has threecontainers. Also a security barrier can be composed of several securitybarriers (1), as shown in FIGS. 1 and 2, such that a longer securitybarrier is obtained. The security barrier (1) as shown in FIGS. 1 and 2is then a standardized construction module by which a security barrierof the desired length can be easily obtained.

The security barrier (1), shown in FIGS. 1 and 2, is composed of a firstand a second construction unit (7 a, 7 b).
